Structural adhesive Redux322 is applied in the aluminum plate and aluminum plate adhesive on a helicopter structural. Due to complexity of the helicopter service environment and the adhesive mechanical maybe decrease due to long-term effects of high temperature and humidity. Floating roller peel resistance is an important test for the aluminum plate and aluminum plate bonding, by comparing floating roller peel resistance changed in the high temperature and moisture environment after the 2000 h, verify structural adhesive Redux322 floating roller peel resistance has no effect from the test results.
